Abstract
This paper describes a straightforward approach for stacking extremely large volumes of sample solutions containing small organic and inorganic anions in capillary electrophoresis. The methodology involves the stacking of large sample volumes and the separation of the stacked anions in an acidic buffer (pH 4 and 1:2.5 × 106) in analytical-grade potassium bromide and boric acid.Keywords
